Claims priority, application Germany, Apr. 3, 1965, H 55,698 14 Claims.(Ci. 2822) This application is a continuation of my co-pendingapplication Ser. No. 333,915, filed Dec. 27, 1963, now US. Patent3,247,568, granted Apr. 26, 1966.

The invention relates to an improved process and apparatus for warpingof short warp threads, in particular, for the manufacture of fabric inmulti-color weaving.

In the process disclosed in my co-pending application Ser. No. 333,915,threads of dififerent colors are wound successively in a single layer.The endless bands thus formed by a group of threads are unwound in atransverse direction after the ends of the wound thread have been gluedtogether. The threads of each loop wound by this process are crossed.Furthermore, the process provides for the simultaneous winding of aplurality of threads.

Although the lengths of the endless bands formed by groups of threads bythe aforesaid process can be adjusted, such adjustments are very limitedin their scope. Thus the adjustment is made by varying the distancebetween winding elements. This change of distance does effectuate anadjustment, but only to a very limited extent, namely a reduction inlength from a maximum warp length to some smaller length. It is thusonly possible to adjust the length of the endless band within thephysicial limitations of the apparatus disclosed in my co-pendingapplication, application Ser. No. 333,915. Furthermore, it should benoted that the adjustment can only be made by changing the position ofthe exterior winding element in the supporting frame with respect to theother Winding element which is a cumbersome operation.

It is a general object of my invention to improve the process disclosedin my co-pending application Ser. No. 333,915 by providing adjustingmeans for adjusting the warp length of the endless bands formed bygroups of threads which do not require a change in position of thewinding elements.

In the apparatus disclosed in my co-pending application Ser. No. 333,915the threads of different color are successively wound in juxtapositionand in one layer. The thus obtained endless warp band is then unwound ina transverse direction. In each of the loops formed around the windingelements the thread is crossed twice. Furthermore, several threads canbe wound simultaneously. The thread drawn from a bobbin is wound aroundthe fixedly mounted winding element in endless form by means of a threadguide, the thread being moved on the winding element and progressingthereon automatically in a transverse direction. The thread guides havethe shapes of tubules and are either manually or by means of grippingdevices transferred from a thread guide support member to the conveyoror device, or are fixedly secured on the conveyor device itself.

It is another general object of this invention to provide an improvedapparatus for warping of short warp threads which has automatic meansfor transferring the preselected thread from a thread guide supportmember to the conveyor device.

Referring now more specifically to the improved apparatus and process ofmy invention, I have designed a machine by means of which warps ofdiiferent lengths can be warped without changing the distance betweenthe axes of the winding elements. The adjustment for the warp lengths iseifectuated by activating and deactivating at will the means forcrossing the wound thread after a pre-selected number of loops have beenwound around the winding elements. Only those threads are cut which havebeen crossed. In the event it is desired to obtain a warp that is longerthan the peripheral distance around the two winding elements plus thedistance ther-ebetween, the thread is wound a pre-selected number oftimes around the winding elements without being crossed by the crossingmeans. The latter means are then only activated during the formation ofthe first and last loop around the two winding elements so that a threadcross is only formed at the beginning and at the end of the warp that isbeing wound a plurality of times around the two winding elements. Sincethe warp threads are only cut at the thread crosses, a warp having alength several times that of a single warp loop is obtained, the overalllength depending on the number of loops that have been wound withoutthread crosses. By means of the aforedescribed apparatus it is possibleto produce warps of different lengths without having to change thedistance between the winding elements, i.e., an apparatus of constantheight or width depending on the arrangement of the machine. Thus theadjustment limitations for the warp lengths are exclusively controlledby the size of the apparatus, i.e., its height or width. It is thereforeadvantageous to make the distance between the winding elementsrelatively small, since multiples of a single warp loop can be easilyproduced. This design criteria makes for warping apparatus of relativelysmall size which results in considerable savings in manufacturing costsand installation space.

The automatic means for transferring the pre-selected thread from athread guide support member to the conveyor device comprise an arm foreach thread of different color which is pivotally mounted in front ofone end of the conveyor device. Each of the aforesaid arms has an eyeletat its free end through which passes a corresponding thread.Furthermore, there is mounted on the frame of the apparatus anadditional member, provided with an eyelet, at about the level of thepivot axes of the pivotally mounted arms which serves to guide a threadto the automatic transferring means. The endless belt of the conveyordevice is provided with a catch hook. By the agency of a rotary magnetor other suitable means a first one of the arms carrying a thread of apre-selected color is pivoted within the range of the catch hook so thatthe latter takes up the thread and winds it in loops around the windingelements. When the color of the warp thread is to be changed, the firstarm is pivoted back into an inactive position by its rotary magnet sothat the corresponding thread can no longer be taken up by the catchbook. The arm of the other selected color is then pivoted into itsactive position wherein the catch hook of the endless belt can take upthe newly selected thread. In this manner the change of color of thewarp threads for the warp is more securely and efficiently effectuated.The aforedescribed arrangement is not prone to malfunctioning because ofits simple operation and construction. Furthermore, the control of theapparatus while operating, has also been simplified.

Several illustrative embodiments of the apparatus and process inaccordance with this invention together with additional objects andadvantages thereof, will be best understood from the followingdescription of specific embodiments when read in connection with theaccompanyiag drawings in which:

FIG. 7 is a side view partially in cross-section of yet anotherembodiment of this invention of a shaft for crossing the threads inaccordance with this invention.

Referring now specifically to the drawing, there is illustrated in FIG.1 an apparatus for warping short warp threads which comprises two sideframe members 1 and 2 and a transverse bottom support frame member 4.The winding elements 5 and 6 which are embodied as deflection cylindersare rotatably mounted. A plurality of bands 9 are movably mounted on thedeflection cylinders 5 and 6 and move in the axial direction withrespect thereto. The conveyor device 12 serves to pick up one of thethreads 37a, b, c, and winds it around the winding elements 5 and 6.This conveyor device '12 is provided with an endless band 13 that runsaround the pair of wheels 14 which are respectively mounted adjacent tothe winding elements 5 and 6. The projecting shaft members 26 and 27 arerotatably mounted in the frame member 2 and are instrumental forcrossing the threads that are being wound around the winding elements 5and 6 as will be described in detail below. The shaft members 26 and 27are provided at their free ends with angular projections 26a and 27a asillustrated in FIGS. 2 and 3. The shaft members 26 and 27 are axiallysupported in the cylindrical support members 28 which are rotatablymounted by means of suitable bearing means, as for example needlebearings 51 inside a second cylindrical flanged support member 50. Arotary magnet 52 is secured by means of a plurality of bolts 52b on asupport plate 53 which is in turn secured by means of a plurality ofbolts 54 to the frame member 2 and is respectively axially connected viaa flange member 56a to the shaft members 26 and 27. The flange member56a is connected to the cylindrical support member 50 by means of aplurality of bolts 56b and is axially connected to the shaft 55 of therotary magnet 52 by means of a wedge key 56.

The control of the rotary magnets 52 for selectively turning the shaftmembers 26 and 27 is coordinated with the movement of the band 13 andthe thread guide secured thereto so that a thread crossing isselectively formed during the winding of the thread about the windingelements 5 and 6. Thus if a warp having the length corre sponding to oneperiphery around the two Winding ele ments 5 and 6 is to be warped thethread crossing is effectuated during the winding of each loop. If,however, a longer warp is to be produced, that is to say a warp having alength which is a multiple of the length of the aforementionedperiphery, an impulse break circuit disconnects the rotary magnets 52 sothat the shaft members 26 and 27 are transferred into a neutral positionin which no thread crossings can be effectuated. The thread is onlycrossed at the beginning and at the end of the formation of a pluralityof loops, that is to say during the formation of the first and the lastloop. Thus, after completion of the multiple run, only the crossedthreads are cut and thereby lets 65a, 65b, 65c

a warp having the length corresponding to a multiple of the single oneperiphery-warp length will have been produced. The control of the rotarymagnets 52 can be effectuated by known electrotechnical means .(notillustrated) such as for example electronic circuitry, relays and thelike. A preselected program of movements for the shaft members 26 and 27can be electrically transmitted to the rotary magnets via the aforesaidknown electrotechnical means by inserting a punched program card 57 intoa receiving slot provided for this purpose in the frame member 2.

The arrangement for changing the threads of different colors isadvantageously provided with an endless band 13 on which there issecured a thread guide 58 which is so shaped that it may act as a threadhook. The latter cooperates with the swingable arms 59a, 59b, 59c. Inthe whole arrangement a sufiicient number of swingable arms are providedso as to correspond to the number of bobbins of thread of differentcolors 36a, 36b, 36c. Each one of the free ends of the arms 59a, 59b,59c is provided with an eyelet 60a, 60b, 60c through which acorresponding thread is guided. Furthermore, a corresponding number ofstationary eyelets are mounted on the frame member 1 at approximatelythe level of the pivot axis of a corresponding swingable arm. Eachswingable arm 59a, 59b, 59c is provided with a rotary magnet 52a, 52b,52c whereby each rotary magnet is connected to a separate independentlyactivatable control circuit. A bobbin support stand 63, which may beembodied as a completely separate structure, serves to support aplurality of bobbins of thread of different colors, which are used forwarping of short warps of diflerent colors. The support stand 63 isprovided with a first group of eyelets 64a, 64b, 64c and a second groupof eyeall of which are mounted on one side of the stand 63, and whichare instrumental in guiding the threads 37a, 37b, 37c therethrough andthrough the stationary eyelets 61a, 61b, 61c on the frame 1 from whencethey are guided through the eyelets 60a, 60b, 60c of the swingable arms59a, 59b, 59c The free ends of the threads of different colors are thenremovably secured, as per glueing, on the movable bands 9 of the windingroller 6, i.e., the winding element.

The swingable arms 59a, 59b, 59c assume the neutral position asillustrated in FIGURES '1 and 4, that is to say in a first positionbehind the guide roller 14. The threads 37a, 37b, 37c run in this firstposition at a substantial distance from the endless band '13,respectively the catch hook 58, to the eyelets 60a, 60b, 60c of theswingable arms. Consequently, in this first position the threads 37a,37b, 37c run substantially along line 66 illustrated in FIG. 4, in whichwhich they can not be taken up by the catch hook 58. If, however, one ofthe threads 37a, 37b, 37c emanating from one of the bobbins 36a, 36b,36c is to be wound around the winding elements 5 and 6, thecorresponding rotary magnet pivots its swingable arm into a secondposition indicated by the dot-dash line in FIG. 4 wherein the threadruns along the lines 67, 68 since the free end thereof is secured to oneof the bands 9. In this manner the thread is run along line 68 so thatthe thread can be taken up by the catch hook 58 which is mounted on themoving endless band 13, and is shifted by the latter onto Windingelements 5 and 6. The other threads remain, however, in the positionindicated by line 66, in which position the threads can not be touchedby the catch hook 58. After the winding operation of a particularpreselected thread has been completed, the corresponding swingable armis pivoted back to its first position by its rotary magnet and anotherpreselected thread can then be swung to the second position by theagency of an other swingable arm and its rotary magnet so that saidother thread is then wound around the winding elements 5 and 6. Theknotting of the first and second preselected threads of different colorsis not required. The Warped threads of different colors thus form amulti-color warp on the winding elements 5 and 6 which can then beremoved from the Winding elements 5 and 6 after having been cut at thethread crossings.

A cover 69 mounted adjacent to the guide wheel 14 aids in guiding thethread.

The swingable arms 59a, 59b, 59c are mounted in corresponding slits 70a,70b, 70c in the frame 1.

There are illustrated in FIGURES 6 and 7 further embodiments of theshaft members 26 and 27 which are instrumental in forming the threadcrossings.

The shaft members, one of which is illustrated in FIG. 6 and isdesignated as 2612, is fixedly, but removably mounted on the framemember 2. The shaft member 26b, which is hollow, is provided at its freeend with a tie rod 71 which is axially movably mounted in the shaftmember 26b. The tie rod 71 is provided at its free end with a hook 72which extends into the path of the catch hook 58. There is mountedinside the hollow shaft member 26b a solenoid 74 and a coil spring 73.The spring 73 axially pulls the tie rod 71 toward the frame member 2,whereas the solenoid 74 pulls the tie rod 72 in the opposite directionwhen activated at a preselected moment. The hook 72 can thus be made toselectively protrude from a slit opening 75 at the free end of the shaftmember 261). The hook 72 has at its front top end an inclined surface76.

The solenoid 74 is activated by a counting mechanism for counting thenumber of loops of wound threads, The counting mechanism is providedwith a photocell (not illustrated) which counts the number ofrevolutions of the endless band 13 i.e., the catch hook 58. The countingmechanism is connected to a switching mechanism (not illustrated) whichalternately activates the solenoids respectively mounted in the upperand lower shaft members which thereby alternately project the hooks 72into the path of the revolving catch hook 58a. Due to the recipro calmovement of the tie rod 71 the thread is positioned alternately in frontand behind the hook 72 on the portion 77 of the shaft member 2612. Thethread which is positioned behind the hook 72 remains on the frontportion of shaft member 26b which has the slit 75. The thread which ispositioned in front of the hook 72 is peeled oft" the portion 77 of theshaft member 26b and thus positions itself behind said shaft member. Thesame operation takes place at the other shaft member which is alsomounted at the same side of the machine. The short catch hook projection58a of the catch member 58 serves to prevent the thread from prematurelyjumping away from the catch hook member 58. The aforesaid catch hookprojection 58a cooperates with the hook 72 of the tie rod 71 in a mannerthat assures that the thread during the reciprocal movement of the tierod 71 is alternatively positioned in front and behind the hook 72. Thethreads are transported due to the transverse movement of the bands 9 inthe direction of the frame 2 which supports the shaft members. Whenwarps of multiple war lengths are being produced by the device of thisinvention, the books 72 of the shaft members 2612, arranged one belowthe other, are alternately reciprocally moved after a preselected numberof revolutions of the band 13.

The embodiment of FIG. 7 illustrates a shaft member 26c which, insofaras the tie rod 71, hook 72, coil spring 73 and solenoid 74 areconcerned, corresponds substantially to the embodiment illustrated inFIGURE 6. The shaft member 26c is provided at its free end with an axialconical projection 78 from which the hook 72 of the tie rod 71protrudes. The operation of the hook 72 of this embodiment is similarlycontrolled by a counting mechanism and a photocell (not illustrated) aswell as by an electrically controlled switching mechanism (notillustrated) by means of which the hooks 72 of both the shaft members260 are caused to alternately be projected forward.

While specific embodiments of the invention have been shown anddescribed in detail to illustrate the application of the inventiveprinciples, it will be understood that the 6 invention may be embodiedotherwise without departing from such principles.
